l-BPA is somewhat transportedinto cancer cells via LAT12 but also takenup by LAT2 (SLC7A8) and ATB0,+ (SLC6A14),16 both of which areexpressed in normal tissues, especially when the concentration of l-BPA is increased.17 Therefore,new boron carriers with better LAT1 selectivity and effective cancercell uptake are needed. The gene discussed is SLC7A5; the disease is cancer.
